Showing unresolved functions in PerfView
Read OriginalThis article explains a PerfView troubleshooting technique for performance analysis. It addresses the issue where all unresolved CPU frames are grouped under a single '?!?' label, which can hide critical performance data. The solution is to launch PerfView with the '-ShowUnknownAddresses' flag, which displays individual addresses for unresolved functions, allowing developers to accurately identify if an unknown function is a major bottleneck or just noise.
